Answer:
Explicit formula is an = 64(-3/4)^(n-1).
Step-by-step explanation:
Looks like a geometric sequence with a negative common ratio.
-48/64 = - 3/4
36 / -48 = -3/4
Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.
The required formula is 64(-3/4)^(n-1) .
The answer is 1:4 because 55 - 11 = 44 so then you have 11 red and 44 green. Take the ratio 11:44 and simplify it to 1:4, and remember order matters. So you can't do 4:1.
X=67.5 or 135/2 or 67 1/2
5h + 2(11-h) = -5
5h +2*11 +2*(-h) = -5
5h +22 -2h = -5
3h + 22 = -5
3h = -5 -22
3h = -27
------
Therefore:
h=(-9), as 3 *(-9) = -27
The awnser is 5 because 7 divided by 35 is 5
